STRIKER FO R ELECTRIC BELLS.

SPECIFICATION forming part. of Letters Patent No. 353,273, dated November 23, 1886.

Application filed January 8, 1886. Serial No. 187,966. (No model.)

To all whom it may concern.-

Be it known that we, CHARLES A. TUoKER, a citizen of the United States, residing in the town of Islip, county of Suffolk, and State of New York, and WILLIAM H. MARKLAND, a citizen of the United States, residing in the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Strikers for Electrical Bells and in Mounting the Same; and we do hereby declare that the following is a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form a part of this specification.

As electrical bells have been heretofore con structed a rigid standard has been provided on the frame on which the parts have been mounted, to the side or face of which standard the spring of the striker has been rigidly secured, and when it has been necessary to adjust the striker, either by bringing the armature closer to the magnet or farther away from the same, this has been done by bending or,

twisting the spring 0. This method of adjust- In the drawings, A is a frame on which the parts are mounted, provided with the magnets B and the usual binding-posts, O G, and bell-standard g, and the striker-rod f is attached to the armature a in the usual manner. The spring 0, which terminates at one end in the circuit-breaker I), is provided at its other end with a sleeve or collar, (1; which is fitted to receive the screw e. This screw 6 is of sufficient length to pass through the collar d and is screwed into the frame A.

In order to regulate or adjust the position of the armature a, and with it of course the position of the striker and striker-rod f it is necessary only to loosen the screw a, turn the parts to the position desired, and then screw them down in that position.

Although we have shown our.invention ap plied to a particular kind of frame in the drawings, we do not limit ourselves to that, as it may be applied to frames of any kind, and may be made and sold as a separate article of manufacture.

Having thus described our invention, what 25 ing thestriker is not only awkward and inwe claim as new, and desire to secure by Letconvenient, so that it is very difficult to set ters Patent, is j the striker in just the position desired, but 1.
